1. Mount bicycle.
2. Ride to local club ride.
3. Meet nice rider who drinks beer.
4. Offer beer in exchange for Dork Disk removal services.
5. Offer more beer for opportunity to learn how to do it yourself.
6. Offer even more beer for opportunity to acquire longterm friendship.
7. Find another rider who doesn't drink.
8. Label second rider "Designated Driver".
9. Repeat steps 4, 5 and 6 for every other basic maintenance task associated with cycling...it's much more fun that way.
...or just get the tools online and sit at home and take it off yourself. Personally I like my method better...
